Global medicine is regressing, and I've become a legend by pulling out cold medicine.

Qin Banban, a distinguished recipient of the National Medal, suddenly finds herself transported into a world where medical knowledge has regressed to an alarming degree. Upon her arrival, she is horrified to overhear her new family earnestly debating whether to cremate their second uncle simply because he has developed a mild fever of thirty-eight degrees Celsius. To her utter disbelief, this society considers such a trivial temperature spike a terminal illness, and an older sister who recently discovered that drinking hot water can lower body temperature is being celebrated as a world-class genius. As Qin Banban explores her new reality, the true extent of the crisis becomes clear: this world entirely lacks basic pharmaceuticals. There are no fever reducers, cold medicines, anesthetics, or painkillers of any kind. Initially paralyzed by a profound sense of helplessness, she eventually decides to act. When she enters a prestigious medical competition armed with something as simple as common cold medicine, the entire globe is left in shock. Her casually formulated ibuprofen is swiftly hailed overnight as a miraculous elixir of life. Governments immediately rush to secure her talents, offering special training and elite protection, while powerful figures from every industry desperately vie for her attention, showering her with wealth, influence, and luxury.
